[LS short box]

I've bought pre bent lines for a couple of projects. When the supplier ships the brake lines they bend them to fit a box of some kind. You have to carefully un-bend.
About the nicopp line. I think its great. Easy to bend and route. Flares like butter. I buy it at Oreillys and they have many different lengths. So as I'm running the lines I buy lengths that are longer than I need. Cut to length and then only need to flare one end.
